+notmuch-sexp-queries
+====================
+
+SYNOPSIS
+========
+
+**notmuch** **search** ``--query=sexp`` '(and (to santa) (date december))'
+
+DESCRIPTION
+===========
+
+
+S-EXPRESSIONS
+-------------
+
+An *s-expression* is either an atom, or list of whitespace delimited
+s-expressions inside parentheses. Atoms are either
+
+*basic value*
+ A basic value is an unquoted string containing no whitespace, double quotes, or
+ parentheses.
+
+*quoted string*
+ Double quotes (") delimit strings possibly containing whitespace
+ or parentheses. These can contain double quote characters by
+ escaping with backslash. E.g. ``"this is a quote \""``.
+
+S-EXPRESSION QUERIES
+--------------------
+
+An s-expression query is either an atom, the empty list, or a
+*compound query* consisting of a prefix atom (first element) defining
+a *field*, *logical operation*, or *modifier*, and 0 or more
+subqueries.
+
+``*``
+``()``
+ The empty list matches all messages
+
+*term*
+ Match all messages containing *term*, possibly after stemming
+ or phase splitting.
+
+``(`` *field* |q1| |q2| ... |qn| ``)``
+ Restrict the queries |q1| to |qn| to *field*, and combine with *and*
+ (for most fields) or *or*. See :any:`fields` for more information.
+
+``(`` *operator* |q1| |q2| ... |qn| ``)``
+ Combine queries |q1| to |qn|. See :any:`operators` for more information.
+
+``(`` *modifier* |q1| |q2| ... |qn| ``)``
+ Combine queries |q1| to |qn|, and reinterpret the result (e.g. as a regular expression).
+ See :any:`modifiers` for more information.
